A supplement to the Iomdin-Lê theorem for singularities with one-dimensional singular locus

Mihai Tibăr (1996)

Banach Center Publications

Similarity:

To a germ f : ( ℂ n , 0 ) → ( ℂ , 0 ) with one-dimensional singular locus one associates series of isolated singularities f N : = f + l N , where l is a general linear function and N ∈ . We prove an attaching result of Iomdin-Lê type which compares the homotopy types of the Milnor fibres of f N and f. This is a refinement of the Iomdin-Lê theorem in the general setting of a singular underlying space.

Some algorithms to compute the conjugates of episturmian morphisms

Gwenael Richomme (2003)

Similarity:

Episturmian morphisms generalize sturmian morphisms. They are defined as compositions of exchange morphisms and two particular morphisms L , and 𝔻 . Epistandard morphisms are the morphisms obtained without considering 𝔻 . In [14], a general study of these morphims and of conjugacy of morphisms is given. Here, given a decomposition of an Episturmian morphism f over exchange morphisms and { L , 𝔻 } , we consider two problems: how to compute a decomposition of one conjugate of f ; how to compute a list...
